Firstly, the cutting accuracy is extremely high, enabling the cutting of complex shapes and fine patterns to meet the demanding requirements for processing accuracy. Secondly, the cutting speed is fast, greatly improving production efficiency. Moreover, its heat-affected zone is small, causing less damage to the material and ensuring the quality of the cutting surface. There are various types of laser cutting machines, such as fiber laser cutting machines and carbon dioxide laser cutting machines, which can be selected according to different materials and processing requirements. At the same time, operating a laser cutting machine requires professional training and strict safety protection measures.

[0003] The prior art such as the utility model with the publication number of CN221019221U discloses a safety protection cover for a laser cutting machine. This patent adopts a protective shell; the protective shell: both the front and rear sides of its upper end are rotatably connected to a rotating shaft through bearings. A rotating seat is provided between the rotating shafts. A sliding groove is formed on the right side of the rotating seat. A uniformly distributed sliding seat is slidably connected inside the sliding groove. A bidirectional lead screw is rotatably connected inside the sliding groove through a bearing.

For this safety protection cover for a laser cutting machine, the clamping seat is adaptively elastically clamped and fixed to the upper end of the laser head through the spring force, avoiding the loosening of the clamping seat and the laser head due to the loosening of the thread at the fixed part of the device. At the same time, the device can adjust the protection angle of the safety protection cover according to actual needs, which is convenient to use, solving the problems that the existing device is in hard contact with the laser head, the laser head vibrates due to the influence of the overall device during the movement process, the threaded part of the device is easily loosened due to the long-term vibration influence, there are potential hazards, and at the same time, the overall structure of the device is fixed, the protection angle of the laser cutting debris is fixed, and it is inconvenient to use.

[0025] The protection component 4 further includes an adjusting unit 42. The adjusting unit 42 includes a limiting block 421 which is fixedly connected to the side surface of the first outer frame 411. A connecting block 422 is fixedly connected to the side surface of the first outer frame 411. Rotation holes are formed in the surfaces of both the limiting block 421 and the connecting block 422. A convex block 423 is fixedly connected to the side surface of the connecting block 422. A guiding groove 424 is formed in the side surface of the second outer frame 413. The convex block 423 is slidably connected to the inner wall of the guiding groove 424. Connecting brackets 425 are fixedly connected to both sides of the second outer frame 413. An adjusting frame 426 is rotatably connected to the inner wall of the rotation hole between the limiting block 421 and the connecting block 422. A limiting rod 427 is rotatably connected to the inner wall of the rotation hole between the limiting block 421 and the connecting block 422. The connecting bracket 425 is threadedly connected to the surface of the adjusting frame 426, and the other connecting bracket 425 is slidably connected to the surface of the limiting rod 427.

[0026] Specifically, the first retaining strip 415 is fixedly connected to the side surface of the upper transparent baffle 412. The first retaining strip 415 is in contact with the side surface of the lower transparent baffle 414. Through the first retaining strip 415, the connecting part of the upper transparent baffle 412 and the lower transparent baffle 414 can be shielded from below, so as to reduce the chance of debris entering the connecting area.

[0027] Specifically, the second retaining strip 416 is fixedly connected to the side surface of the lower transparent baffle 414. The second retaining strip 416 is in contact with the side surface of the upper transparent baffle 412.

[0028] In this embodiment: Through the second retaining strip 416, the connecting part of the upper transparent baffle 412 and the lower transparent baffle 414 can be shielded from above, so as to reduce the chance of debris entering the connecting area.

[0029] Specifically, the number of the limiting blocks 421 is two. The two limiting blocks 421 are symmetrically arranged about the first outer frame 411.

[0030] In this embodiment: The number of the connecting blocks 422 is two. The two connecting blocks 422 are symmetrically arranged about the first outer frame 411. The connecting blocks 422 are in contact with the side surface of the second outer frame 413. The number of the convex blocks 423 matches that of the connecting blocks 422.

[0033] Working principle: When the cutting machine needs to be protected, the installation frame 2 is sleeved on the cutting head of the cutting machine, and the fixing bolt 3 is tightened. The fixing bolt 3 cooperates with the installation frame 2 and the connecting block 1 to limit the protection component 4 at the cutting part, so as to block the sparks generated during the cutting of the equipment; when the cutting height of the equipment changes, the adjusting frame 426 is rotated. The adjusting frame 426 meshes with the connecting frame 425. Under the action of the adjusting frame 426, the connecting frame 425 pushes the second outer frame 413. The second outer frame 413 pulls the other connecting frame 425. The other connecting frame 425 moves under the guidance of the limiting rod 427. At the same time, under the guidance of the connecting block 422 and the convex block 423, the second outer frame 413 drives the lower transparent baffle 414 and the second baffle 416 to move. When the second outer frame 413 abuts against the surface of the workpiece, stop rotating the adjusting frame 426. Then, during the processing of the equipment, the first outer frame 411, the upper transparent baffle 412, the second outer frame 413 and the lower transparent baffle 414 will block the sparks generated by the equipment. By setting the protection component 4, the height of the protective cover can be adjusted according to the cutting height of the equipment, thereby reducing the problem that it is difficult to block the gaps at high places when the protective cover adopts an integrated design and the equipment adjusts its height, and further improving the protection effect of the protective cover.
